CHARLES PALMER, OF LONDON, ENGLAND, ASSIGNOR TO THE NATIONAL CASH REGIS-TER COMPANY, OF DAYTON, OHIO, A CORPORATION OF OHIO, (INCORPORATED INCASH-REGISTER.

To all whom it may concern:

Be it known that I, CHARLES PALMER, a subject of the King of GreatBritain and Ireland, residing at London, in the county of Middlesex,England, have invented certain new and useful Improvements in CashRegisters, of which I declare the following to be a full, clear, andexact description.

This invention relates to cash registers and more particularly to thetype of machine shown in the patent granted to Cleal and Reinhard, No.580,378, April 13, 1897.

There is considerable demand for a small sized machine, that is one oftwo or three banks of keys, that will perform all of the functions ofthe type of machine shown in the above mentioned patent, but owing tothe wide separation of the movable elements of the totalizing mechanism,such a small machine has so far been impracticable and the principalobject of this invention is to provide the patented type of machine witha compact totalizing mechanism so that the total registering capacitythereof may be greatly increased.

Another object of this invention is to provide such a type of machinewith mechanism for operating a totalizing mechanism of the type shown inthe patent granted to Thomas Carney, No. 497,860, May 23rd, 1893, sothat the parts of these machines, which are in extensive use, may becomeinterchangeable, that is as far as the totalizing mechanism isconcerned.

Vith these and incidental objects in view the invention consists incertain novel features of construction and combinations of parts theessential elements of which are set forth in appended claims and apreferred form of embodiment of which is hereinafter described withreference to the drawings which accompany and form Part of thespecification.

Figure 1 is a central transverse sectional view through a machine of thetype shown in the Cleal and Reinhard patent with the improvementsapplied thereto. Fig. 2 is a partial top plan view of the totalizingmechanism and its cooperating parts. Fig. 3 is a detail elevation of themain rotary shaft and its connect-ion with the operating rock shaft.

Described in general terms the machine comprises a series of banks ofmanipulative devices or keys which determine the move- Specification ofLetters Patent.

ment of oscillatory'segments which are actuated upon the rotation of anoperating crank handle. These segments mesh with intermediate gearswhich in turn mesh with pinions secured to indicators to indicate theamount represented by the operated manipulative devices or keys.Connected to the intermediate gears are spiral cams which operateregistering segments differentially. Prevlous to the movement of theseregistering segments by the spiral cams, totalizing elements mounted ina rock frame are carrled into engagement with said segments, so as tohave the movement of the segments imparted to the movable elements ofthe totalizing mechanism. At the beginning of the operation of themachine the spiral cams are returned to normal or zero position with theindicators, the segments in turn following the spiral cams by means ofcoil springs, the totalizing elements in the meantime being disconnectedfrom said segments. With this brief description of the mode of operationof the machine it is thought it will be much easier to follow thedetailed description which follows.

The manipulative devices or keys 1 are held in their outermost positionby springs 2 coiled about the shanks of said keys. Upon depressing anyone of these keys its inner end will project into the path of a pawlforming a part of the latching mechanism 3 attached to the registeringsegment of that particular bank of keys. Upon the operation of a crankhandle 4 (see Fig. 2) a main operating shaft 5 will be rotated throughsuitable intervening gears 6. At the end of the shaft on the oppositeside of the machine from the crank handle 4 is a disk 7 to which issecured one end of a link 8, the other end of such link being secured toan arm 9 fast upon a shaft 10 which is suitably supported in theframeworkll of the machine. As the shaft 5 rotates in the direction ofthe arrow shown in Fig. 3 the shaft 10 will rock first in one directionand of the depressed key, at which time the latching mechanism will bedisengaged from its segment 12 so as to allow the latter to complete itsmovement. Each of the segments 13, of which there is one for each bankof keys, engages with an intermediate gear 14, which in turn meshes witha pinion 15 suitably secured to an indicator 16. From this it will beseen that the differential movement of the segment 13 as controlled byits value keys will be imparted to its indicator 16 through the gearingjust described. All of this mechanism is fully shown and described inthe above mentioned Cleal and Reinhard patent, and for a furtherdetailed description thereof reference may be had to said patent.

The intermediate gears 14 (see Fig. 2) are attached to hubs 17 whichsurround a horizontal shaft 18. Secured to one end of each of these hubs17 is a spiral cam 19 which is arranged to engage with an antifrietionroller 20 projecting laterally from a fork-shaped arm 21. At its forkedend each of these arms 21 is arranged to straddle sleeves 22 connectedto the intermediate gears 14 and through which the type carriers, asshown in the Cleal and Reinhard patent, are set up. At its other endeach of the arms 21 is connected to a segment or actuating device 23 forthe totalizing mechanism but the arm 21 controlling the cents actuatingsegment 23, as shown in Fig. 2, is connected to an arm 24 projectingupwardly from a hub 25 which is secured to a transverse shaft 26 towhich is also secured cents registering segment 23. The dimes anddollars registering segments are loosely mounted upon the shaft 26. Therollers 20 projecting from the arms 21 are held in contact with theperiphery of the cams 19 by springs 27. The spring 27 of the centsregistering segment is connected at one end to the arm 21 and its otherend to the back frame of the machine, while the springs controlling thedimes and dollars segments are connected to the rear ends of links 28projecting from the segments and to the back frame of the machine. Fromthis description it will be-seen that the movements of the intermediategears 14 will through the spiral cams 19, rock the segments 23 adistance depending upon the extent of movement of the segments 13 whichare geared to the intermediate gears 14.

Just previous to the registering movement of the segments 23 a frame 29carrying totalizer wheels or elements 30 will be rocked about its pivots31 by a link 32 which is connected at one end to an arm 33 extend ingdownwardly from the frame 29. The rear end of the link 32 is forked andstraddles the main shaft 5. Projecting from the link 32 is a roller 34which extends into a cam groove 35 formed in a disk 36 secured to theshaft 5. The shape of the groove 35 of the disk 36 is such that thepinions 37 secured to the wheels or totalizing elements 30 will berocked into engagement with the segments 23 before their registeringmovement and held in such engagement during the movement of suchsegments 23 after which the pinions 37 will be rocked out of engagementto permit of an independent movement of the totalizing elements by theirtransfer pawls 38. These pawls are pivoted upon a short rod 39 mountedin the registering frame 29 and have downwardly extending portions whichproject into forked forward ends of links 40, the rearward ends of whichare also forked so as to straddle the shaft 5 and be operated thereby.Near their forward ends the links 40 have upwardly and forwardlyextending portions 41 which pass over a transverse rod 42 so as to guidethe forward ends of such links 40. Each of these links is provided witha roller 43 which is operated by a cam 44 secured to the main shaft 5.These cams 44 are arranged upon the shaft 45 so as to actuate thetransfer pawls 38 successively, as is well known in the art and fullydescribed and shown in the before mentioned patent to Thomas Carney. Thetransfer pawls 33, of which there are two, are arranged to transfer fromthe units to the tens and from the tens to the hundreds. The transfersfrom the hundreds to the succeeding wheels are effected by Geneva stopmovements, as is well known in the art. The links 40 are held in theirrearward position with their rollers 43 in contact with the periphery ofthe cams 44 by coil springs 45 the ends of which are secured to hooksformed on the links and to a cross rod 46 mounted in the rear of themachine.

It will readily be seen that by providing one type of machine with partsthat may be used in another type of machine, although the functionsperformed by one of the said machines are more comprehensive than theother, a considerable saving will be made in the amount of stock that isnecessarily carried to build these machines and also repairing of saidmachine is more easily accomplished. Further, the machine as constructedwith the type of totalizer herein shown is much narrower and thereforetakes up much less space when placed in use.

Vhile the form of mechanism herein shown and described is admirablyadapted to fulfil the objects primarily stated it is to be understoodthat it is not intended to confine the invention to the one form ofembodiment herein shown and described as it is susceptible of embodimentin various forms all coming within the scope of the claims which follow.
